Its a convention to indicate that this variable is not for general 
use.
It is part of the internal implementation of the class or module.

But it is only a convention and Python will not stop you from
accessing it. It is similar to the convention of using all uppercase
letters to indicate a constant value that should not be changed
by users of the code.

HTH,
